ES20 features a 1" Terylene Soft-Dome Tweeter and 1 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the Elysian 1 features a 27x90mm" AMT (Ribbon) Tweeter and 1 x 7" Coated Fiberglass Woofer with a Crossover frequency at 2500Hz.
Frequency Response
ES20 has a frequency range of 41-40k Hz whereas Elysian 1 has a frequency range of 49-22k Hz. With a minimum frequency of 41Hz, the ES20 can go significantly deeper on the low side and provide stronger bass compared to the Elysian 1's min frequency of 49Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
High Frequency
Bookshelf Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
ES20 is a 8 ohms speaker compared to the Elysian 1 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Elysian 1 can provide this impedance level.
These two speakers also have different sensitivity levels. ES20 sensitivity is rated at 86 dB and the Elysian 1's is rated at 89 dB. This 3 dB difference makes the Wharfedale Elysian 1 a more sensitive speaker compared to Polk ES20, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
ES20 can handle a max power of 175 watts RMS from the amp the whereas ES20 has a max power handling value of 125 watts RMS , 50 watts less than the Elysian 1.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Elysian 1 features Binding post posts which make bi-amping or bi-wiring possible. ES20 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Wharfedale Elysian 1's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
ES20 has a rear firing port whereas Elysian 1 has a bottom firing ports. Wharfedale Elysian 1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk ES20 with its rear-firing port.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Polk ES20's and Wharfedale Elysian 1's external dimensions. Polk ES20 has external dimensions of 375.0 x 218.0 x 351.0mm ( 14-3/4 x 8-9/16 x 13-13/16inch) whereas Wharfedale Elysian 1 has external dimensions of 458.0 x 264.0 x 316.0mm ( 18-24 x 10-3/8 x 12-7/16inch) .
Polk ES20 is 46mm narrower and 83mm shorter than Wharfedale Elysian 1 but it is also 35mm deeper.
Below you can see the front view size comparison of Polk ES20 and Wharfedale Elysian 1 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Polk ES20 is approximately 765.2cm2 / 118.6inch2 and base area of the Wharfedale Elysian 1 is approximately 834.2cm2 / 129.3inch2. The ES20 requires 8% less surface area than the Elysian 1 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Polk ES20 weighs 7.73kg / 17lbs and the Wharfedale Elysian 1 weighs 15.03kg / 33.1lbs. This makes the Elysian 1 94% heavier than the ES20.
Here is a comparison of how ES20 and Elysian 1's weights compare with the average, max and min weights in Passive Bookshelf class.
